ANTIFRICTION SIDE BEARING FOR RAILWAY CARS.

No. 90am.

' Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed May a, 1908. Serial No.-&31,669.

.5 mm, have invented a new and useful Imower bearing plate and G loose separating firovement in Antifriction Side Bearings for ailway-Cars, of which the following 'is a specification.

My invention relates to anti-friction side 0 bearings for railway cars.

In anti-friction railway side bearings of the kind heretofore commonly in use, difficulty is experienced and ineflicient operation 00- casioned by reason of the fact that the rollers 5 interposed betweenthe upper and lower side bearing lates do not materially operate to reduce t e friction due to the side thrust or lateral thrust of the train in rounding curves.

My invention consists in the means I em- 0' ploy to practically accomplish this object or result. tion with upper and. lower side bearing plates, the former secured to the body bolster and the latter secured to the truc bol- 5 ster, of an interposed rotatable. disk journaled to rotate upon the lower side bearing plate, said lower side 'bearingplate being pro- 'vided with a plurality of oppositely or differently inclined annular treads and the ro- 0 tatable disk having also a plurality of differently inclined annular treads, and a plurality of sets of anti-friction rollers interposed between the several annular treads of the lower bearing late and the rotatable disk.

5 The invention i iirthe'r consists in the novel construction of'parts and devices and in the novel combinations of parts and devices hereshown and described. -In the accompanying drawing forming a 0 part of this speclfication, Figure 1 is a front elevation of a car truck and-body bolster,

with my improved anti-friction side be F' 2 l l l a 1g. is a. contra vertica on tudinal section throu hone of the side be i- 5 mgiiTand Fig. 3 is a p an vieywpartly broken away. In the drawin ,A re resents the truck bolster and A the Tod olster.

B is the lower bearing plate secured to the 0 truck bolster, the upper bearing plate secured to the body bolster, D the interposed rotatable disk journaled upon the lower bearing plate F F F anti-friction rollers interosed between said rotatable disk andzthe That is to say, it consists in connec rings placed between the several sets or series of anti-friction rollers.

The lower'bearing plate B, which is secured to the truck bolster, is provided with an annular hub b, the axis of which is somewhat inclined from the vertical towards the center of the car, and withan annular rim 1). Between the annular hub and rim b the lower bearing plate B is furnished with a plurality V of differently or oppositely inclined annular treads b and than also preferably with anintermediate annular tread b.

, The inter osed rotatable disk D has a central stud or ubd, preferably of conical shape, fitting within the'annular hub b of the lower side bearing plate B, audit is also provided with an outer marginal rim (1 which embraces or telesoo s over the annular rim 6 of the lowerside caring plate B. The rotatable disk D is further provided with two oppositely inclined annular treads (1 (P, and

preferably also withhn intermediate annular tread d, these annular treads being referably parallel to the annular treads b 3 b of the lower bearing late B.

' The upper bearingcfaoe d of the rotatable disk D is preferably rounded or curved'about as indicated in 2, and the lower bearing plate B and rotatable disk D are so arranged and combined with the upper side bearing C on the body bolster that said side bearing C contacts with the rotatable disk D only at the portion thereof outside of its axis or pivot stud or hubd, as will be readily understood from Fig. -1 of the dra As the axis of the rotatable disk I) is inc ined to the vertical, the disk D is also of course inclined to the horizontal. p 4

The rotatable disk D is referably secured to the lower bearing plate of said disk-D after the parts are assembled and secured in place by a riveting or clenching flange d which is bent over the connecting ring H or upset in respect thereto.

As the annular treads b b and d d of the plate B and disk D are oppositely inclined, the two sets of rollers F and F axes oppositely inclined and serve to effectually and anti-frictionally resist the side thrust of the train in rounding curves, as well as to anti-frictionally resist the weightor direct dowfiward load of the car on the side bearings. The intermediate set of rollersfF cooperate with the sets of rollers F p by aconnecting 5 ring H which is applied to the-central stud d ave their 7 and F, affording an anti-friction bearing under the weight or downward load of the car.

The rings G fit loosely between the several sets of rollers F 1 F These rings are preferably made wedging in cross section so that their faces g may be more nearly at right angles to the axes of the differently inclinedrollers F F W. The rollers F F are each preferably furnished with rounded beveled or tapering end faces f to diminish their contacting bearing against the separating rings G and the faces of the rim on the huh I).

I claim 1. The combination with car truck and body bolsters, of lower side bearing plates secured to the truck bolster, upper side hearing plates secured to the bodybolster, interposed rotatable inclined'disks journaled on the lower side plates with their axes inclined to the vertical, each of said lower side plates and each of said rotatable disks having a plurality of differently inclined annular treads, and a plurality of sets of anti-friction rollers, substantially as specified.

2. The combination with car truck and body bolsters, of lower side bearing plates sccured to the truck bolster, upper side bearing plates secured to the body bolster, interposed rotatable inclined disks journaled on the lower side plates with their axes inclined to the vertical, eachof said lower side plates and each of said rotatable disks having a plurality of differently inclined annular treads, and a plurality of sets of anti-friction rollers, and separating rings between the different sets of anti-friction rollers, substantially as specified.

3. The combination with car truck and body bolsters, of lower side bearing plates secured to the truck bolster, upper side bearing plates secured to the body bolster, interposed rotatable inclined disks journaled on the lower side plates with their axes inclined to the vertical, each of said lower side plates and each of said rotatable disks having a plurality of differently inclined annular treads and a plurality of sets of anti-friction rollers, and separating rings between the different sets of anti-friction rollers, each of said lower side bearing plates having a central hub and a rim, and each of said rotatable disks having a-cooperating central hub and rim, substantially as specified.
